Severe constipation for 2 weeks, need advice

For 2 weeks, going on three, I have severe constipation. In my whole life I had not very much constipation or diarrhea. I'm not dehydrated or malnourished. I drink lots of water, real juice, eat pretty healthy, eating more fruits and veg as of late, even have one cup of coffee in the am, fiber drink in the am, stool softener at max dose, had to resort to laxatives and when that didn't work, an enema. ( Ouch!) I even was prescribed a powder laxative and didn't work well. I'm still doing everything instead of fiber drink. Even got suppositorys if the enima doesn't work. idk what to do. I'm in pain on and off in my back and after I eat my stomach starts to hurt too. I see the doc again this week. Anyone have had this problem?
